Thebarometer works bybalancing the weight of mercury in the glass tube against the atmospheric pressure, much like a set of scales. Atmospheric pressure is basically the weight of air in the atmosphere above the reservoir, so the level of mercury continues to change until the weight of mercury ...
How many atmospheres of pressure is 112,000 Pascals? How many moles of air must be pumped into a 4.8 L tire to give it the pressure of 47.1 psi at 25 degrees C? Convert 73.5 cm Hg to atm and psi. The pressure 85.0 m under water is 935 kPa. What is the pressure in atm and wha...
pascals are not convenient to most everyday pressure measurements. Atmospheric pressure, for example, measures approximately 101,325 Pa, or 101.325 kilopascal (kPa). This is equal to 1 atmosphere, or1 atm.
The standard constant value which is used to measure atmospheric pressure at sea level is one atm. Those one atm is equal to one lakh one thousand three hundred and twenty five \[(101325)\] pascals. And this one atm is also almost equivalent to \[29.9213\]inches of mercury. We can co...
Calculate how much pressure (due to the liquid) would be on a 73-kg person if they were 234 m deep in: a. freshwater. The density of freshwater is 1000 kg/m3. Express your answer in both pascals and atmospheres. b. saltwater. The density of saltwater is 1 ...
in 2003. the vertical axis represents the pressure that it takes to obliterate the rock, measured in mpa, or millions of pascals (to go from mpa to atmospheric pressure, just multiply by 10). the horizontal axis has to do with how porous the rock is. the figure includes data ...
In a vacuum environment, the absolute pressure of the gas is much lower than the typical atmospheric pressure at sea level, which is about 101,325 pascals (Pa) or 14.7 pounds per square inch (psi). The atmosphere is mostly nitrogen and oxygen, but when dealing with vacuum chambers, we mu...
Furthermore, the millimetre of mercury is still routinely used in medicine, aviation, meteorology, and many other scientific fields. In addition, one millimetre of mercury is approximately 1 Torr which is 1 / 760 of standard atmospheric pressure (101325 / 760 ≈ 133.322368421053 Pascals). ...
3. Normal atmospheric pressure at sea level is generally considered to be equal to the pressure exerted by a column of mercury 760mm high. Calculate the corresponding pressure in inches of mercury and in Pascals. 4. The hydraulic lift in a service station is capable of raising cars with a...
pressure-patterns are as important as they are down here at the surface. Atmospheric pressure is simply an expression of the force applied by a column of air upon a fixed point of known area, and is measured in pascals (Pa). Meteorologists use the hectopascal (hPa) because the numbers are...
